Stupid rails question: undefined method in class declaration

Question

I have a user class where I am trying to attach a profile created by a factory. Here is the class:

class User < ActiveRecord::Base
  acts_as_authentic
  has_one :profile

  after_create {self.profile = ProfileFactory.create_profile(self.role)}

end

and the factory is as follows

class ProfileFactory
    def self.create_profile(role)
      String s = "#{role}#{"Profile"}"
      Object.const_get(s).new
    end
end

For some reason, he does not recognize himself as a user. This is the error I get when calling ProfileFactory.create_profile

undefined "role" of the method for #<Class:0x2304218>

The user object has the role: String declared in its migration.

Any help is appreciated.

Answer 1

The object Userpassed to the block after_createis passed as a parameter.

class User < ActiveRecord::Base
  after_create do |user|
    user.profile = ProfileFactory.create_profile(user.role)
    user.save
  end
end
